Re: 2095: "Marsiforming"

"Marsiforming" doesn't sound like it would be the right word to me, but Mars is the Latin name for the god, so I guess also for the planet? Should it instead be something like "martaforming"? Areforming. At least that would be my choice. The etymology doesn't quite line up, but ...
